The return of coupons is mainly divided into the following four situations:

1) A refund is initiated while the order is in progress. If all the items in the order, the coupon will be returned to the customer, and the validity period will not change. If the validity period has passed when the refund is made, the coupon will not be returned

2) A refund is initiated while the order is in progress. If only part of the order is refunded, the coupon will not be returned

3) A refund is initiated after the order is completed, and the coupon will not be returned

4) If the order is not paid or is closed over time, the coupon will be returned to the customer, and the validity period will remain unchanged. The coupon will not be returned if the validity period has passed when the refund is made.

5) When some coupons are refunded or orders are canceled, if the same coupons already exist in the account, the coupons will not be returned.
